Magnetoresistance of the Double-Exchange Model in Infinite Dimension
نویسنده
چکیده
Double-exchange model in infinite dimension is studied as the strong Hund’s coupling limit J → ∞ of the Kondo lattice model. Several quantities such as Green’s function and the d.c. conductivity are calculated in analytical forms. Magnetoresistance in lightly doped La1−xSrxMnO3 is reproduced very well.

The La0.75Sr0.2Mn1-xCoxO3 (0 ≤ X ≤ 1) Manganite-Cobaltites are synthesized by sol-gel method and their structural, electrical and magnetic properties are studied. After calcination over 800 ºC, all compounds were crystallized in the perovskite rhombohedral structure ( R3C, Space group). Due to nonstochiometery, some traces of the La2O3 phase were appeared in final samples. Resistivity meas...

In this paper after introduction of manganites, we have studied the effect of particle size and doping on structural, magnetic and magnetoresistance of LSMO manganite samples. The magnetoresistance measurements show that, by decreasing the particle size LFMR increases. Also the results show that the LFMR increases at low doping levels and decreases at high doping levels. The spin dependent tun...

متن کاملCritical Exponents for the Ferromagnetism in Colossal Magnetoresistance Manganites
Critical phenomena of ferromagnetic transition in colossal magnetoresistance manganites are theoretically studied. Concerning the critical exponents for this transition, there still remains controversy among experimental results. In order to clarify intrinsic physics of the manganites through a comparison with theoretical prediction, we investigate the critical phenomena of double-exchange mode...
